ICAO APAC PBCS Workshop October 20 Controls & Indications common to FANS A+ and B+ A 380/A 350 Commonality with A 320/330/340 operating principles A 350/A 380 Cockpit interactivity = More efficient workflow Page 5 © AIRBUS Operations S. All rights reserved. Confidential and proprietary document.

ICAO APAC PBCS Workshop October 20 Demonstration of compliance with RCP/RSP • For latest FANS 1/A+ (resp. FANS B+) developments, ED-122/DO-306 (resp. ED-120/DO-290) specifications are used as a basis Demonstration that RCP/RSP allocations to the Aircraft are met are part of the aircraft FANS function airworthiness approval • ATC Data Link systems and FANS function certification are required but not sufficient to operate FANS on an aircraft • Operational approval, under operator responsibility, is required • Conditions of use may affect the actual performance of the avionics equipment (e. g. if significantly different from assumptions taken for avionics certification) • Tests are made using a representative ground ATC simulation Some end-to-end tests are performed with real ground ATC systems, but not exhaustively of course Page 6 © AIRBUS Operations S.

ICAO APAC PBCS Workshop Demonstration of compliance with RCP/RSP • Demonstration strategy • Availability, integrity and continuity requirements Basically by demonstrating : - Fulfilment of the Safety Requirements - Adherence the minimum required Development Assurance Level process (to meet Safety Objectives) - FANS function continuity requirement supported by compilation of qualified failure rates for equipment involved in the function Page 7 © AIRBUS Operations S.

ICAO APAC PBCS Workshop October 20 Demonstration of compliance with RCP/RSP • Demonstration strategy • Time Aircraft contribution to the Transaction Time is allocated to each contributing avionics equipment to the function, function e. g. : - From Comm Means up to Display Systems for uplink processing - From Generating Systems (e. g. FMS) up to Comm Means for downlink report sending Actual time performance of the avionics chain is compiled to ensure compliance with Aircraft requirements from ED-122 / DO 306 and/or ED-120 / DO-290 Additionally, for major changes to the function, end-to-end tests using real networks (in lab and/or in flight) are performed to ensure overall good behaviour and compliance with expected performance requirements Page 8 © AIRBUS Operations S.

ICAO APAC PBCS Workshop October 20 Configuration Management of FANS certification • FANS certification is maintained up to date • Each time an equipment contributing to the function is upgraded • Each time a new equipment contributing to the function is added Note: This only applies when the change is supported by an aircraft MOD approved by Airbus. • Any potential effect on Safety, Performance, Interop and/or HMI qualification is assessed • If any impact is identified, the FANS function airworthiness is • reassessed New approval is requested including the new or upgraded equipment contribution Page 9 © AIRBUS Operations S.

ICAO APAC PBCS Workshop October 20 Operational notion of RCP/RSP in the cockpit NONE • Aircraft is providing the flight crew with alerts in case of equipment/capability failures, failures e. g. • Comm Means failure (e. g. SATCOM FAULT) • Definitive connectivity loss (e. g. VHF 3 DATALINK FAULT) • Failure of ATC Data Link (e. g. ATC DATA LINK FAULT) BUT • There is no consolidated RCP/RSP capability directly displayed to the flight crew Appropriate procedures (refer to GOLD) and associated training shall be in place to ensure adherence with RCP/RSP monitoring requirements Page 10 © AIRBUS Operations S.
